Lore:

Takwa was just trying to go back to the old days, until they got kidnapped by her imaginary friend, he mimicking her family and friends hated her and tortured her, and make her insane and anxiety, she started to freaking out, before she injecting perseverance, she can't take it anymore, making the imaginary friend to stop, until they killed anyone or just being insanity.
